中文摘要:

伴随着水环境污染,水体中藻类疯长形成的"水华"、"赤潮"现象日益严重。各种化学、物理、生物方法被用于抑制藻类的生长,但这些方法都存在不易控制、成本高、易破坏生态等问题。利用植物化感作用抑制藻类生长具有生态安全和灵敏高效等优点,对湖泊富营养化的生态控制具有非常重要的意义。作者介绍了植物化感抑藻的研究进展,归纳了化感作用的种类和化感物质的化学成分,并讨论了植物化感抑藻的作用机制、抑藻机理,最后对植物化感作用在抑藻方面的研究前景进行了展望。

英文摘要:

With the serious water pollution,the "algal bloom","red tide" formed by the overpopulation of algal is getting worse.At present,different methods including chemical,physical,biological were used to inhibit the growth of algae in polluted water.However,the characteristics of these methods are difficult controlling,high cost,and damaging the ecology.In order to develop a low cost and ecologically safe method to inhibit the growth of algae,plant allelopathy is introduced.In this review,the research progress of algal-inhibition with plant allelopathy was introduced,the types of plant allelopathy and the chemical composition of allelochemicals were summarized,the mechanisms and perspective of plant allelopathy were discussed.
